2012 was the hottest year since 1895. That’s 117 years by my count. Of course just being the hottest year ever recorded does not mean everywhere was warmer than usual. Some places were cooler. And the New York Times looked at the US pattern of warmer and cooler than average temperatures. Below the map are small multiples of charts recording the number of days above or below the normal for that day.
And for anecdotal evidence, I will say that this past summer was godawfully hot in Chicago.
Today the London Underground turns 150. The Tube opened on 9 January 1863. Yes, the whole endeavour is a marvel of engineering, but from a design perspective think of the map, man. Think of the map. The Underground map is now 150 years old. And we all know transit maps are cool.
Of course the map has evolved and changed over all those years and at the Huffington Post UK, there is an article with a slideshow of different maps. The one below being the first map to show the combined lines.
Compare that original system map to the 150th anniversary map.

Have you ever wondered what you would do if you caught a US citizen who was a terrorist? No? Well, the folks at the Brookings Institution did and using what is publicly known and inferring from events that have happened they have created a disposition matrix about the decisions made in such scenarios. In short, it is an interactive flowchart with examples and explanations of the various steps.

I’m back after two weeks holiday. See, I didn’t forget you. I even brought you presents. Of a sort. From National Geographic come two maps from an article about the poaching of elephants—if I recall correctly.
The first map is the better of the two. It shows the impact of poaching by overlaying the ranges of the elephants in two different years. Not surprisingly, the range has decreased. The map also points out monitored reserves and then aggregates data from those sites into regions, whose illegal death totals are displayed as little filled-in elephant icons. I don’t love the icons, but they are compact, flat, and stack nicely. Almost squarish. So they can work for me.
This second map is less successful. It dedicates a lot of real estate to a large map that is really only used to highlight countries that are quite large. Without any kind of supplemental data as the first map had, e.g. the elephant ranges, I would have likely made the map smaller. The tusk chart below the map…yeah.
Both taken together, I am left with the impression that the full-page graphics were the work of two different hands. The first map has the level of detail of someone who is conversant in and works regularly on infographics. The second page feels a bit weaker, as if from someone not quite so familiar with infographics and how to make the best of them.
The New York Times looks at who controlled the redistricting of US congressional seats because of the 2010 census. It then showed an example in North Carolina where Republican control led to the state being less competitive in the past for Democrats. In 2010, Democrats held 7/13 seats in North Carolina. But after the redistricting, in 2012 the Democrats held only 4/13. And all of this is done in a small, compact space. This is a very effective graphic.
Yesterday the Washington Post published an article and an accompanying interactive infographic on life expectancy. But not just how long one can expect to live, but also how long one can expect to live in good health. What makes the piece particularly nice and effective are the annotations that explain some of the data points, in particular the outlier of Haitian males.

Earlier this week, the Office of National Statistics in the United Kingdom released census results for England and Wales. (Northern Ireland and Scotland are reported separately.) England has more people than expected, most likely because of undercounting of immigrants, and Wales is now some three million and counting. There are fewer Christians than expected—and fewer Jedi than I expected—as the ranks of the non-religious grow. But from of course all of this comes a bevy of visualisations. These are but a few, but if anybody finds others worth nothing, please feel free to send them my way.
Straight from the source is a set of interactive mapping applications from ONS that compare 2001 data to 2011 data. As best it can, census districts are compared on a one-to-one basis, but with boundary changes that isn’t always possible. Clicking on district provides one with details about the responses for that area.
Perhaps the one thing missing from these—and it may well owe to the aforementioned boundary changes—is a map of changes to see which areas have been most impacted. Or a map of the results compared to the average to see where the average can be found and where the positive and negative extremes can be found.
An infographic from the Guardian looks at the overall dataset with quite a few maps and then circle-y things. While the large map is the white population in 2011, the remaining maps are before and after comparisons. Again, an interesting look would have been perhaps deviations from the average or of the actual change per district.
I appreciate the impact of the main story, the increasing diversity of England and, to a lesser extent, Wales. London in particular is now minority white. However, I am less keen on the circle-y things and that data could probably have been presented in a clearer, more direct fashion. I am not a fan of red, yellow, and green traffic light colours, but I also recognise that the Guardian is working within their brand on this.
Unfortunately this interactive map of Northern Ireland’s national identity does not quite work for me. I appreciate the toggle between the different response options, however, I find the responses themselves hard to compare. The colours remain the same, but the scales for the results change. For those identifying as Northern Irish, the top value is clearly less than those identifying as either British or Irish. But I would have liked to have seen the scales for British and Irish to closer match. I also find the black background distracting and overwhelming the colours. I wonder how the result would have worked if treated with the above aesthetic.
The BBC took a stab too with a section devoted to the results. Unlike the ONS visualisation above, however, the side-by-side comparison is forced to be smaller with the included text. And when one zooms into a particular district, the map degrades into crude polygons—a particular pet peeve of mine—that would be unrecognisable to someone familiar with the intimate geographic details of their home region. (Yes, simple shapes make the files smaller for overview maps, but when seen up-close, they lose their value by making ugly maps.) Also, the colours and bins in this particular view are not as informative as in the view above.
The BBC, however, did create a small graphic for an article that showed population changes in the districts, alas the colours did not work as well as one would hope.
That’s a lot for people to digest, but, overall I think the clearest visualisations go to the ONS. They lack the commentary that can be brought by journalism organisations, e.g. the BBC, but one needs a clear and powerful visualisation before one can start writing an analysis.
